Background Medical ethics deals with the ethical obligations of doctors to their patients, colleagues and society. The annual reports of Sri Lanka Medical Council indicate that the number of complaints against doctors has increased over the years. We aimed to assess the level of knowledge, attitude and practice regarding medical ethics among doctors in three teaching hospitals in Sri Lanka. Methods A hospital-based cross-sectional study was conducted among doctors using a pre-tested self-administered, anonymous questionnaire. Chi Squared test, and ANOVA test (...) were used to identify the significance of association between level of knowledge and selected factors. Results Most doctors had a poor level of knowledge on medical ethics, with postgraduate trainees showing significantly higher level of knowledge. The average knowledge on medical ethics among doctors was significantly different between the three hospitals. Over 95% had a favourable attitude towards gaining knowledge and advocated the need for training. The majority indicated awareness of unethical practices. 24.6% of respondents stated that they get a chaperone ‘sometimes’ during patient examination while 3.5% never do. The majority responded that they never accept gifts from pharmaceutical companies in recognition of their prescribing pattern. 12–41% of doctors participated in the study acknowledged that they ‘sometime’ engaged in unethical practices related to prescribing drugs, accepting gifts from pharmaceutical companies and when obtaining leave. Conclusion Most doctors had a poor level of knowledge of medical ethics. Postgraduate trainees had a higher level of knowledge than other doctors. The majority showed a favourable attitude towards gaining knowledge and the need of training. Regular in-service training on medical ethics for doctors would help to improve their knowledge on medical ethics, as well as attitudes and ethical conduct. (shrink)

Evolutionary developmental biology (evo-devo) has undergone dramatic transformations since its emergence as a distinct discipline. This paper aims to highlight the scope, power, and future promise of evo-devo to transform and unify diverse aspects of biology. We articulate key questions at the core of eleven biological disciplines—from Evolution, Development, Paleontology, and Neurobiology to Cellular and Molecular Biology, Quantitative Genetics, Human Diseases, Ecology, Agriculture and Science Education, and lastly, Evolutionary Developmental Biology itself—and discuss why evo-devo is uniquely situated to substantially improve (...) our ability to find meaningful answers to these fundamental questions. We posit that the tools, concepts, and ways of thinking developed by evo-devo have profound potential to advance, integrate, and unify biological sciences as well as inform policy decisions and illuminate science education. We look to the next generation of evolutionary developmental biologists to help shape this process as we confront the scientific challenges of the 21st century. (shrink)

High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

Language’s intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production (...) of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans.

As the expansion of the Internet and the digital formatting of all kinds of creative works move us further into the information age, intellectual property issues have become paramount. Computer programs costing thousands of research dollars are now copied in an instant. People who would recoil at the thought of stealing cars, computers, or VCRs regularly steal software or copy their favorite music from a friend's CD. Since the Web has no national boundaries, these issues are international concerns. The contributors-philosophers, (...) legal theorists, and business scholars, among others-address questions such as: Can abstract ideas be owned? How does the violation of intellectual property rights compare to the violation of physical property rights? Can computer software and other digital information be protected? And how should legal systems accommodate the ownership of intellectual property in an information age? Intellectual Property is a lively examination of these and other issues, and an invaluable resource for librarians, lawyers, businesspeople, and scholars. (shrink)

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

This article introduces a new hybrid intake procedure developed for posttraumatic stress disorder (PTSD) screening, which combines an automated textual assessment of respondents’ self-narratives and item-based measures that are administered consequently. Text mining technique and item response modeling were used to analyze long constructed response (i.e., self-narratives) and responses to standardized questionnaires (i.e., multiple choices), respectively. The whole procedure is combined in a Bayesian framework where the textual assessment functions as prior information for the estimation of the PTSD latent trait. (...) The purpose of this study is twofold: first, to investigate whether the combination model of textual analysis and item-based scaling could enhance the classification accuracy of PTSD, and second, to examine whether the standard error of estimates could be reduced through the use of the narrative as a sort of routing test. With the sample at hand, the combination model resulted in a reduction in the misclassification rate, as well as a decrease of standard error of latent trait estimation. These findings highlight the benefits of combining textual assessment and item-based measures in a psychiatric screening process. We conclude that the hybrid test design is a promising approach to increase test efficiency and is expected to be applicable in a broader scope of educational and psychological measurement in the future.

Patient safety has only recently been subjected to wide-spread systematic study. Healthcare differs from other high risk industries in being more diverse and multi-contextual, and less certain and regulated. Also many patient safety problems are low-frequency events associated with many, varied contributing factors. The subject of this paper is the epistemology of patient safety (the science of the method of finding out about patient safety). Patient safety research is considered here on the background of a risk management framework which requires (...) researchers to: • Understand the context - as a subset of healthcare quality, services and systems research, with technical and human behavioural (cultural) components and a range of external and internal organisational influences, a wide range of research disciplines is necessary • Identify the risks - identify the things that go wrong and the frequency and nature of different types of incidents from sources such as medical record review, observational studies, audit, incident and medico-legal reports • Analyse the risks - deconstruct the things that go wrong, identifying contributing factors and trying to detect trends and patterns in contributing factors, detection, mitigation factors, ameliorating factors and actions taken to reduce risk • Evaluate the risks - decide on priorities, identifying preventive and corrective strategies and judging the risk- and cost-benefit of potential corrective strategies such as standardisation or simplification of a process or device • Manage the risk - evaluate and scope preventive and/or corrective strategies and then implement these, or place the problem on a risk register pending solution, or accept that what is needed is unaffordable • Communicate and consult - use interactive sessions, audit, on-going feedback, reminders and patient mediated prompts • Monitor and review the state of the problem - get baseline trends and patterns so that changes can be tracked and properly attributed to an intervention A hierarchy of levels of evidence has been proposed for clinical research and we argue that insufficient weighting has been given to lower ranked levels of research and to qualitative research, although critical interpretive synthesis is now gaining acceptance in mainstream thinking (e.g. by the Cochrane Collaboration). Fundamental challenges remain including how to grasp the elusive concept of patient safety, how to quantify, characterise and cost the problems, how to judge the extent to which harm can be attributed to errors, violations or system failures, how to identify contributing factors and the extent to which they can be implicated, how to judge whether incidents or their precursors are preventable, how to generate strong evidence to make healthcare safer and how to translate research into practice. Future directions include addressing the mundane as well as rare, dramatic events, and developing further research in non-hospital settings and in developing countries. In summary, a mixture of qualitative and quantitative methods, using information from all available data sources and combining retrospective, real time and prospective study designs, is necessary to address some of the more difficult patient safety problems.

(Report assembled for the Workshop of the AMIA Working Group on Formal Biomedical Knowledge Representation in connection with AMIA Symposium, Washington DC, 2005.) Best practices in ontology building for biomedicine have been frequently discussed in recent years. However there is a range of seemingly disparate views represented by experts in the field. These views not only reflect the different uses to which ontologies are put, but also the experiences and disciplinary background of these experts themselves. We asked six questions related (...) to biomedical ontologies to what we believe is a representative sample of ontologists in the biomedical field and came to a number conclusions which we believe can help provide an insight into the practical problems which ontology builders face today.

The idea of structural analysis of the Aeneid has been attacked recently by some who believe that too complicated mathematics are involved in line totals involving a golden mean. The object of the present article is to investigate whether simpler numerical effects are discernible in the poem, and whether these effects were deliberately inserted by Virgil. The significant numbers to be examined in this connexion are 3, 7, 12, and 30. The first three of these are among the ritualistic numbers (...) whose use in the Aeneid was discussed by C. P. Clark, while 30 is among other things part of the series 3, 30, 300 which we encounter in Aen. I. 261–96. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Could Understanding Harm?Iskra Fileva, PhD (bio) and Linda A.W. Brakel, MD (bio)We would like to thank the editors for organizing this symposium and our commentators—Marga Reimer and James Phillips—for the thought-provoking feedback. Although we had thought about the ideas we discuss from many different angles, our commentators raised several interesting issues we had not considered. We are grateful for the opportunity to continue the conversation.Reply to ReimerAs Professor Reimer (...) notes, we advocate an approach to self-constitution that we dub “understanding first.” On this approach, non-moral and non-normative understanding of the origin of maladaptive traits must precede moral evaluation and attempts to free oneself—or as we say “prune”—undesirable traits. Professor Reimer presents several interesting cases meant both to extend and test the limits of our proposal. We appreciate this approach and respond to each case in turn.Genes and AlcoholismSuppose Alejandro, an adult raised by adoptive parents, struggles with alcohol addiction. He learns that his biological parents died of alcoholic liver disease and comes to believe that his alcohol problem is caused by a genetic propensity toward alcohol abuse. One can ask: “Does an understanding first approach have the potential to undermine the sense of agency that is necessary for the effective treatment of maladaptive traits?”Answer: It can be explained to Alejandro that genetic proclivities are just that—proclivities—that can be overridden. In fact, behavior can alter our very genes—although not at the sequence level— changes known as “epigenetic.” And the liver disease of the biological parents can serve as a cautionary tale. If even in light of these considerations, Alejandro’s tendency to see genetic propensities as deterministic persists, it is worth asking why. There is no evidence that “genes are destiny,” so the disposition to see them that way must have a psychological explanation. What is the explanation? A self-destructive desire? Fear of freedom? This exploration can itself be empowering. [End Page 211]Adaptive ForgettingSuppose Beata, who has an eating disorder, was molested by her own father when she was a child. Subsequently, her father shot himself and now she has no recollection of the molestation. However, Beata’s eating disorder is largely a result of those experiences. It is quite possible that if Beata were to recall being molested, that would do more harm than good. In this connection, one can ask together with Reimer: “Does an understanding first approach have the potential to undermine an adaptive ‘forgetting’ of root causes of maladaptive traits?”Answer: Here, understanding the history, instead of forgetting it, might allow Beata to gain insight into and empathize with possible motives that may have led to becoming obese. For example, she might have the phantasy that if she had been obese and unattractive, she could have prevented the molestation—hence, become that way now to prevent it from happening again, and more wishfully reverse it. (In unconscious goings-on time is thought to be in the “unexamined present” (Brakel 2009, p. 63; 2015, p. 131; 2022, p. 4; 2023, p. 404.) One benefit of this is that in gaining this type of recognition, Beata might find it easier to change her behavior that she otherwise would not have; it was never her responsibility to prevent her own molestation, and there is no reason whatsoever for her to now make herself unattractive to her deceased father, and very little reason to remain obese in an attempt to deter current day men.Ego-Syntonic Maladaptive TraitsClaire is a concert pianist and alcoholic. Importantly, Claire does not see her own desire for alcohol as destructive but rather, as something constitutive of her own identity. “I wouldn’t be myself without alcohol,” she says. Reimer asks whether our approach would “work for cases where the agent sees a maladaptive trait as constitutive of their identity?”Answer: Although no approach can guarantee success, our claim is that our approach has a better chance than the main alternative known as the pruning view. Since Claire, by stipulation, is not inclined to see her own drinking as a problem, a... (shrink)

A scholarly edition of a work by Adam Smith. The edition presents an authoritative text, together with an introduction, commentary notes, and scholarly apparatus.

The sixth decade of this century may be considered a period of dynamic development of the Soviet ethics. In contrast with the post-revolutionary period, the ethics does not limit itself to a normative reflection, but starts also extensive studies in the theory of ethics. According to the authors of the present article, there are all reasons to believe that the marxist ethics will become a scientific discipline in a full sense of the word. The purpose of the article is not (...) to discuss all problems involved in the contemporary Soviet ethics, but above all to outline main problems and trends of its development. The authors distinguish following aspects of the ethical investigations: philosophical, sociological, social-psychological, axiological, pedagogical, historical, gnoseological, logical, and metaethical. Together with a critical evaluation of solutions of certain problems, they criticize some abstractive and ahistorical, in their opinion, approach to ethics which has been manifested above all in works of Y. A. Milner-Irinin and P. M. Egides. (shrink)

The year 1666, on Newton’s own testimony, was the "wonderful year" wherein, at the tender age of 24, he developed the fundamental principles of the integral calculus, verified the composite nature of sunlight, and satisfied himself by calculation that the earth’s gravitation holds the moon in its orbit. Fittingly to commemorate the third centenary of that year, and at the same time to bring together the considerable results of recent Newtonian scholarship, Robert Palter organized a symposium at the University of (...) Texas in Austin on November 10-12, 1966. The proceedings of that symposium, including sixteen major papers by scholars of international reputation and the comments they elicited from learned colleagues, first appeared in The Texas Quarterly, Vol. 10, no. 3 ; they are now made available to a larger reading public in this book, many in revised and expanded form. Not all of the contributions will interest the philosopher, but the attention of those specializing in the philosophy of science is directed particularly to R. S. Westfall’s and I. B. Cohen’s scholarly articles on Newton’s optical theories and on his force concept respectively, both of which contain considerable material for philosophical analysis. Of more general significance are Palter’s own treatment of Newton’s inductive method, Howard Stein’s analysis of Newtonian space-time, and J. H. Randall’s reflection on the religious consequences of Newton’s thought. One of the most stimulating articles is Dudley Shapere’s evaluation of the philosophical significance of Newton’s science, made in the context of his on-going debate with T. S. Kuhn and P. K. Feyerabend, which sheds yet further light on the problems of meaning invariance and scientific change.—W. A. W. (shrink)
